About the Company

Armadin

AI-native platform for proactive cyber defense

Armadin provides an AI-native cybersecurity platform that helps large enterprises prepare for AI-driven cyber threats. Its system uses a swarm of specialized AI agents that simulate attacker behavior to continuously reason, plan, and adapt, seeking exploitable vulnerabilities and kill chains across an organization’s attack surface. Unlike traditional scanners, Armadin’s agents return proof of what can be exploited, enabling proactive remediation and a reduction in testing time from days to minutes. The company differentiates itself through autonomous, attack-minded AI that operates at machine speed, combining red-teaming expertise with AI research to detect and validate risks across multi-modal, rapid campaigns (hyperattacks). The goal is to shift security from reactive checks to proactive, continuous testing that keeps pace with AI-enabled threats, serving Fortune 100 enterprises on a subscription basis.
